For the reaction N2O4(g) 2 NO2(g), Kc = 0.21 at 100 C. At a point during the reaction, [N2O4]=0.12 M and [NO2]=0.55M. Is the reaction at equilibrium? If not, in which direction is it progressing?

Respuesta :

What is the equilibrium constant?

The equilibrium constant shows the extent to which reactants are converted into products.

In this case, we must find the reaction quotient as follows;

Qc = [0.55]^2/[0.12] = 2.5

Since the Qc > Kc, it means that the reverse direction is favored in this reaction.
